To all whom 'it may concern: A

Be it lknown that we, DENNIS WILLIAM DALEY, CHARLES. ALEXANDER lGUNN, and FRANK RICHARD DALEY, citizens of the United States,iresiding at Pittsburg, in the vcounty of Allegheny r`and State of Pennsylvania, have invented certain new and useful Improvements in a CombinedA Water Heater and Still; and we do declareY the following to m be a full, clear, and exact-description ofthe invention, such as-will enable others skilledA in the art to which it appertains to make and use the same, reference being had to the ac-` companying drawings, and to the letters and i5 figures of reference marked thereon,which parts, all of which will be first fully described and afterward specifically pointed out in the I o appended claims. Referring to the accompanying drawings,

Figure 1 is a vertical sectional view of our device. Fig. 2 is a similar view showing a slightl modification, and Fig. 3 isa detail sec- 3 5 tional view ofthe steam-tank-valve-controlling mechanism.

Like numerals of reference indicate the same parts throughout the several figures, in

` which- 4o. l indicates the device, which comprises the hot-water tank 2, water-back or heater 3,

steam-tank 4,' and charcoal-can 5.

As shown in the drawings, the hot-water tank 2 is connected to the water-back or 45 heater 43 by means of a pipe 6, within which l pipe isa three-wayivalve 7. Passing upwardly from'said'valve 7 is a pipe 8, which connects with the bottom of the steam-tank 4, a pocket 9 being'formed in said steam- 5o tank at the oint of entrance of said pipe 8. As shown, t e vsteam-tank 4 is constructed,

preferably, of two sections `1U and 11 which are suitably flanged and cou led together means of bolts' 12. Y' Secure Within the 11p-1 per section 10 and preferably resting ontan 55 annular flange 13 in the-lower section' 11 is a charcoal-cane, which is filled preferably with charcoal or other suitable material, the

bottom 15 of the 'can 5l being perforated, as

shown. Referring nowto .the hot-water 6o tank 2, it' will be seen thatafcoil 16 is ar- 1 ranged within said tank, the ends of the coil passing out through the ends ofthe tank through suitable stuffing-boxes 17, said coil 16 being connected to the upper section l0 65A I of the steam-tank ,4 by means of a steam'linepipplS. eferring now to the water-back or'heater 3, it will be seen that the said water-back or heater is connected to 'the steam-tank by--7o means of a pipe 19, within which pi eis located a three-way .valve 20, and. a so convnected to said valve 20 is a pipe 21, which forms the hot-water line 22, and connect-ed to the hot-water line 22, preferably at a point 23, is a filter 24, which filter is connected to the steam-tank4, as shown. Within the steam-tank 4 is a valve-float 25, secured 'to a lever 26, fulcrumed at 27, said lever being connected to a valve-stem 28,-Fig. 3, the 8o valve and seat being located within the valvecasing 29, as shown in Fig. 1.`

Referring again to the water.- back or heater 3 in connection with the steam-tank 4, it will be seen that a defiecting-plate 30 is 85 arranged above the ipe 19, which connects the heater or water-back 3 with the steamtank and it will also beseen that thethreeway valve 7 and three-way valve 20'are'co'nnected together by means of a link 31, a 9o single handle 32 on the valve 20 being arranged sotliat both valves 7 and 20 are operated simultaneously by a single movement. Referring to the hot-water .tank 2, it will be seen thatbelowthe bottom thereof the` coil 16 connects with the pipe 33, -which forms `a trap and which is provided with a l flared outlet or nozzle 34,. and itwill also be seen that a pipe 35, leading to the domestic IOO top thereof. Referring again to the valve 7, it will be seen that the sediment-tank 36 is be seen that in place of connecting the waterback or heater 3 directly with the steamtank 4, as shown in Fig. 1 and as before described, a coil 37 passes through said steamtank 4 and is connected to the hot-water line 22, a valve 38 bein provided so as to shut OH the connection. t will also be seen that a trap 39 is provided in the pipe 6', which connects the hot-water tank with the water-back or heater 3.

Having thus described the several parts of 'our invention, its o eration is vdas follows:

Referring particular y 'to Fig. 1, it will be seen that when it is desired. toemploy the device for a simple domestic heater the valves Tand 2O are provided, so as to cause a direct connection between the hot-Water tank 2 and the water-back or heater 3, the valve 7A shutting 0H connection between the pipe 8 and the water-back or heater 3. At the'sarne time said valve 7 is moved the valve 20 is moved so as to close the connection between' the steam-tank 4 and the water-back or heater 3 and to open connection between the water-back'or heater 3 and the hot-water line 22. Following the connections therefor it will be seen that the water passes from the hot-water tank 2 into the water-b ack or heater 3, where it is heated and passes out of the`water-baek or heater 3 into the hot-water line 22, where the water again enters the hot-water tank 2 near .the top thereof. By this arrangement, therefore, we have a simple domestic water-heating apparatus. When, however, itis desired to Ause the device as a water-still, the valves 7 and 20 are turned so as to close connection between the pipe 6 and the water-back or heater 3, and at the same time the valve 20 is turned so as to close the connection between the hot-water line 22 and the waterback or heater 3, At the same time that this .connection is closed connection is opened between the' steam-tank 4 and the waterback or heater 3 through the valve 2() and connection is opened between the steamtank 4 and the water-back or heater 3 through the valve 7 Following these connections, therefore, it will be seen that the water passes from the water-back or heater 3 into the steam-tank 4 and back from the steamtank 4 into the water-back or heater 3 through the pipe 8 and valve 7. As the water is heated 1n the water back or heater 3 it passes up into the steam-tank 4, strikes the deflecLing-plate 30, sov as to prevent disturbance at the surface of the water in the with the device in order to keep the temperasteam-tank 4 .and also for the purpose of deflecting any sediment down into the pocket 9. As the water boils in the steam-tank 4 the steam passes through the perforated l 2, which illustrates a Y bottom 15 of the charcoal-can and through I the charcoal into the steam-line 18 and down through the coil 16 in the hot-water tank 2, where the steam is condensed,v producing the distilled water, which finds its outlet through the fiared nozzle 34, said nozzle being' preferably perforated to aerate. the water. The heat given up from the condensing-coil 16 raises the temperature of the water in the,` hot-water tank, beginning at `the top, where the hot-Water supply for the fixtures is taken off throughj'the pipe 35, thus utilizing all the waste heat .without heating the water-supply excessively. 'The water in the hot-water tank 2 being under pressure kpasses from the hot-water tank through the hot-water line 22, up through the filter 24, and into the vsteam-tank 4, at which point *he How of water is controlled bythe float-valve. 2-5, so that. the water in said steam-tank is always kept at a uniform height. in Fig. 3, the valve-stem' 28 and the valvelever 26 extend within the steam-tank 4, the working parts of the valve being on the outside of thetank and within the valve-casing 29, Fig. 1.

The operation of the modification shown in Fig. 2 is substantially the same as we just described for Fig, 1, with the exception that when it is desired to utilize the device as a simple domestic water-heater the valve 38 is turned so as to close connection between the hot-water line 22 and the bottom of the hot.- water tank. Thus the water passes from the bottom .of the hot-water tank through the pipe 6 into the water-back or heater 3., through the coil 37 in the steam-tank 4 and into the hot-water line 33,'back again into the hot-water tank 2. Vlihen utilizing this construction as a water-still, the valve 38 is turned so as to shut off connection between the top of the hot-water tank and the coil. 37 in the steam-tank 4. The water therefore passes from the water-back or heater 3 through the coil 37 in the -steam-tank 4, through the valve 38, down through the lower portion of the hot-water line 22 into` the pipe 6, Vback into the heater 3, the trap 39 preventing the hot-Water from entering the bottom of the hot-water tank 2. In this construction the water in the steamtank 4 is brought to the boiling-point by the coil 37 therein,- and the steam passing from the water in the steam-tank 4 finds its way through thecharcoal into the condensingcoil 16 precisely the same as before described, and the height of water in the steam-tank 4 is controlled by the valve-float 25 and the valve the same as before described.

If desired, any suitable apparatus, such as thermostat, may be employed in connection ture of the water uniform andv prevent waste of heat when water is not being drawn off for use.
